Indeed - this is a known requirement for VMs (certainly under KVM, I don't
know about Xen etc, but I would assume it also applies there).

Whether you consider it a shortcoming of Debian (and therefore Devuan) that
acpid and acpid-support-base are not installed by default is up to you.

My solution is that I've added these packages to the script I run immediately
after creating a VM, to make sure it works the way I want it to.
